World Rivers Day, World Rivers Day is an annual global celebration of the world’s waterways, observed on the last Sunday in September. Established in 2005 by the internationally renowned river conservationist Mark Angelo, World Rivers Day highlights the global importance of rivers and aims to increase public awareness and encourage greater stewardship of rivers around the world.

Celebrating World Rivers Day

Millions of people in more than 60 countries celebrate World Rivers Day. Here at ARKive, we’ve joined in by talking to Kevin Smith, a Programme Officer with the IUCN Freshwater Biodiversity Unit, to find out more about the importance of rivers and the main issues they face.

‘Ribbons of life’

Rivers underpin many freshwater ecosystems and play a critical role in sustaining the lives of thousands of different species and habitats worldwide. Despite their importance, rivers and their associated freshwater ecosystems are actually extremely rare. Only 3% of the world’s water is fresh water, and freshwater ecosystems account for less than 1% of the planet’s total surface area.

Riverine habitat

According to Kevin, “Rivers – and freshwater habitats in general – are real hotspots of biodiversity. They may only cover 1% of the Earth’s surface, but they support almost 10% of the world’s known species. These ribbons of life also provide livelihoods and economic benefits to billions of people across the world through what are known as ‘ecosystem services’ such as fisheries, water filtration or even tourism.”

Rivers shape the landscape; act as drainage channels; and transport fresh water and nutrients to lakes, wetlands and other freshwater habitats before eventually flowing out to sea. They provide the stage for some of nature’s most spectacular events, such as the annual migration of salmon from the sea to their spawning grounds upstream. Rivers, and the fresh water they contain, are also vital to human wellbeing, providing the water we drink, as well as sources of food, recreation and energy.
